Glass printbed

Depron bed insulator.

Printrbot screwdown.

xt60 power plug.

Hot bed standoff and glass clamp.

Z axis micro switch jabber.

Fan adapter.

New carriage assembly.

Spool A-frame.

Wobble fixed.

I found the main cause of the wobble which has annoyed me for months.

The "wobble" turned out not to be a sideways movement at all but uneven lift was cause the layers to bulge every Z-motor revolution.
The Z-motors rock slightly on their flimsy mounts. The fact the hole aren't in the right place doesn't help.
The threaded rod and smooth rods aren't parallel causing the shaft coupling to flex every revolution.
My temporary fix is 4 wedges glued in place.
The results are pretty good.printrbot
